uMap VS MapSVG

I haven't tried but I bet you could also import it into a uMap. Source: about 1 year ago

If you prefer not to use proprietary, walled-off services like Strava I recommend Umap which has some great map editing Functionality and allows sharing links or even exporting the maps as JSON. Source: over 1 year ago

I'm not hosting it myself but I'm using the open-source OSM uMap (https://umap.openstreetmap.fr/en/) with a custom layer that points to a GeoJSON endpoint on my webserver. Source: over 1 year ago

That being said, http://umap.openstreetmap.fr/en/ exists. This is a website where one can make a small map, personal or shared with friends who can edit. Source: over 1 year ago

Open Street Map iframe of a custom map (https://umap.openstreetmap.fr/en/) with an external layer that points to an endpoint on my server. The server takes my database of points/labels/etc and serves it in GeoJSON format for OSM to understand and render. Source: over 1 year ago

I think that site uses https://mapsvg.com/ for their map plugin. Source: almost 2 years ago

I customized something called MapSVG. The map itself is a vector image I drew, the planets I created in and exported from Grand Designer, and I heavily styled the popups to contain a lot of information and look like Mass Effect's codex. Source: about 3 years ago
